Marea Alcalina
A competent technical user can build a useful self-hosted catalog+WhatsApp order flow (and there are repo starting points), but reproducing Marea Alcalina’s full polished product, hosted reliability, AI studio credits and multi-plan billing is a multi-week effort and may not be worth reimplementing for most users.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Marea Alcalina alternatives, with the arithmetic →
What a replacement has to do
- Publish a product catalog page, accept customer selection, send order summary to shop owner via WhatsApp or email, record orders in a database, and optionally accept card payments.
What it still won’t have
- Marea Alcalina’s hosted reliability, uptime SLAs and operational support
- Built-in marketing/AI Studio credits and proprietary 'Marea IA' assistant
- Trust signals (Trustpilot reviews, verification badges) and branded marketplace presence
- Polished multi-catalog/product limits, billing controls, and prebuilt templates
- Ongoing product improvements and customer support
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted digital-catalog service using Node.js (Express) + Postgres + React. Core features: product CRUD (images, price, variants), public catalog pages per store, cart that opens WhatsApp with a prefilled order message and falls back to email, record orders in Postgres, admin dashboard for orders with filtering and basic product/stock analytics, Stripe + PayPal checkout and webhook handling, account signup and plan flag for product limits. Out of scope: multi-tenant billing engine, advanced AI content studio, and Trustpilot/review aggregation. Include proper error handling, input validation, webhooks tests, unit tests for payment and order flows, Docker-based deployment, and a setup script to configure DNS and Stripe keys.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
